How to Create Transparant soap

VCO can also be used to make transparent soap. transparent soap made from VCO will be safer because it does not contain high doses of chemicals. The basic reaction is the saponification ie soap making 3NA OH + (C17H35COO) 3C3H5) → 3C17H35COONa + C3H5 (OH) 3  SODA SODA stearate glyceryl stearate glycerin.
